We look at the division of 729496 by 73 
The aim is to understand the frequency of 73 in 729496.

Moving on to step 1:
The number 73 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 73

Going ahead to step 2:
If we divide 72 by 73, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 73

Advancing to step 3:
When dividing 729 by 73, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 657 from 729 to get 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 73

Going ahead to step 4:
724 divided by 73 is 9 with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 657 from 724 leaves us with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 73

Going ahead to step 5:
679 divided by 73 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 999.0
If we take 657 away from 679, we end up with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 73

Step 6:
73 can be fit into 226 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 9993.0
If we take 219 away from 226, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 73, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 9993.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
700 divided by 73 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 9993.09
Deduct 657 from 700 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
If we divide 430 by 73, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 9993.095
Subtracting 365 from 430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
When dividing 650 by 73, we get 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 9993.0958
If we subtract 584 from 650, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
73 goes into 660 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9993.09589
Deduct 657 from 660 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
73 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 9993.09589
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
73 goes into 300 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9993.0958904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
73 can be fit into 80 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 9993.09589041
If we subtract 73 from 80, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 9993.09589041 and a remainder of 7e-09.
